One of Seth's close friends said Seth always carried a flash drive in his pocket. The cops didn't list a flash drive among the items that were found on Seth. It was not found in his condo. And how could his computer vanish? It was PW protected and the cops couldn't get in so they gave it to the FBI!

Was it the flash drive that contained the date he uploaded from the DNC server and that's what the murders took. Cops were right, it was a robbery for a flash drive.
